LIVE-STEA'M FEED-WATER PU RIFIER.

SPECIFICATION forming part of Letters .Patent No. 423,606, dated March 1.8, 1890.

Application filed June 1l, 1389. Serial No. 313,840. (No model.)

To all whom t may concern: t

Be it known that I, CHARLES G. HAsKIN, av citizen of the United States, residing at Evanston, in the county of Cook and State of Illinois, have invented certain new anduseful of division into contact with highly-heated surfaces in the presence of live steam, whereby it is heated to a point sufficient to liberate therefrom most of the carbonates and some other matters held in solution. The Water after being thus acted upon passes downward into the deposit-chamber, where the carbonates for the most part are retained, and it then ascends through a body of coke or other suitable filtering material, which completes the separation of any precipitated matter and renders the water clean and bright. I attain these objects by the mechanism represented by the accompanying drawings, in Which'- Figure' l is a vertical section ofthe purifier, a central portion broken away. Fig. 2 is a top view of the splashers or spraying-plates, and showing also the water inlet and distributing nozzles. Fig. 3 is a cross-section on line 3 3 of Fig. 1. Figs. 4 and 5 aredetail views of two forms of spray-plates, and Fig. 6 is a plan view of a perforated diaphragm used in the device. Fig. 7 is a detail view of a ring used to support the spray-plates.

A is the out-er cylinder or shell, which may be built of boiler-iron or steel, and has a water-inlet B, a steam-inlet C, man-holes and plates at D D D, purified-water outlet E, and blow-off F.

G is a perforated diaphragm forming the depositing-chamber H at the bottom. From G, by preference, in the center rises the pipe J, terminating ina funnel-shaped diaphragm K, fixed to angle-iron supports L. The pipe J, passing through the diaphragm G, forms theY annular chamber M in which coke or other suitable filter-ing material may be placed.

of solution.

The diaphragm G is perforated to allow the water to ascend through the annular chamber M to the exit at E.

N is an inner cylinder, preferably constructed in annular sections O, connected by bolt-flanges P, and having a yseries of splashers or spray-plates Q, arranged one above the other, and staggered or alternated and connected together by the rings o o. The top ring is extended, as shown, to the same diameter as the outer cylinder, thereby causing the whole of the Water to descend within said inner cylinder; also preventing the steamfrom circulating into the space above said inner cylinder until it has already acted upon the water in circulation therein. Thel ends of the splashers or spray-plates pass through rectangular apertures o in the rings o o, said apertures providing for the admission of steam from the annular space I I into the inner cylinder N. (See Fig. 7.) The splashers or sprayplates may be conveniently constructed from channel-irons, in sections similar to Fig. 4, or of corrugated sheet metal, as shown in Fig. 5, and in the latter case I use, by preference, brass or copper, and by placing them in staggered or alternating positions, as shown, the maximum spraying and heat-ing effect upon the water is obtained. The water-inlet B may be divided into two or more nozzles R; or any equivalent arrangement, such as a perforated rose, may be conveniently used.

S is the top of the outer cylinder, fastened thereto by bolts or in any other convenient manner, whereby it canv be easily removed for inspection or cleaning.

In operation I pass the unpurified Water through the water-inlet B. It is divided by the nozzle R into two or more streams, which fall upon the top series of splashers or dividing-plates Q, and from these it falls upon each succeeding lower series, becoming sprayed or broken up into a fine state of division. At the same time I pass live steam' through the steam-inlet C, which fills the annular space T between the inner and outer cylinders, and passes therefrom through the apertures between the splashers or dividing-plates Q, meeting and'heating the finely-divided Water under operation thus causing the carbonates and some vother impurities in the water to fallout The mixture of water-precipi- IOO tates, and condensed steam then pass downward through the pipe .I into the depositchamber I-I. I-Iere most of the above-mentioned precipitates fall to the bottom and the water rises through the perforated diaphragm G and the coke or filtering material contained in the annular space M to the exit E, whence it is drawn olf to the boilers. During its passage lthrough the iltering material contained in M it becomes purified from' any precipitate which escapes settling in the depositchamber H, and iiows from' the exit E clear and bright. the deposit-chamber H may be blown off from time to time through the outlet F.

1. In a live-steam feed-water purifier, the combination, with a closed outer vessel having an inlet-pipe for unpurifled Water, of an interior cylinder or vessel located below the inlet-pipe and open at top and bottom, said interior vessel or cylinder having interior parallel s pray-plates or splashers having their ends projected through the walls of ysaid inner vessel or cylinder, and forming apertures for` the admission of steam therein, substantially as described.

' 2. In a live-steam feed-water purifier, the combination, with the outer cylinder or vessel having steam and water inlet pipes and The sediment which collects inv an inner cylinder having its upper end flared or extended out to the walls of the outer cyland having its upper end ared or extended outv to the walls of the outer cylinder to close the annular space between the two, and an inlet for'steam into the said annular space.

'4. In a live-steam feed-water puriier, the combination, with aclosed outer vessel, of an interior cylinder or vessel open at top and bottom, and itted internally with parallel spray-plates or splashers,.and havingopenings inits vwalls for the admission of steam, and its upper end flared or extended out to the walls of the .outer cylinder, said outer cylinder having induction-pipes for steam and unpuriiied water and an eduction-pipe for'puriied water, substantially as specified.
